Strategy: OnBarUpdate not fired for last plotted bar

[fwalton]

I have a strategy which does not fire OnBarUpdate for the last daily bar.
It is now Sunday 6/28, but still Friday 6/26 session bar event is not fired, even though it is drawn on the StrategyPlot.

Example:

Create new chart, instrument = "MSFT", Period = Daily, BarsBack = 2

Strategy code:
protected override void Initialize()
{
CalculateOnBarClose = true;
BarsRequired = 0;
}
protectedoverridevoid OnBarUpdate()
{
string logText = "";
logText = String.Format("Instrument:{0} CurrentBar:{1} Date:{2}", Instruments[BarsInProgress], CurrentBar, Time[0]);
Log(logText, LogLevel.Information);
}


Output:
Category Message
Default Instrument:MSFT Default CurrentBar:0 Date:6/25/2009 00:00:00

Changing the BarsBack property results in the OnBarUpdate event firing for all bars except the last one.
If BarsBack is set to 1, this error occurs:
Error on plotting last value for indicator 'StrategyPlot'. Please check the 'OnBarUpdate' method: Index was out of range. Must be non-negative and less than the size of the collection.

Should not OnBarUpdate fire for the last completed bar?

Hello,

The line of code below is stopping it from calculating again until the bar closes. The data provider has not sent the bar close/ bar open event yet, so NT does not calculate the bar yet:
CalculateOnBarClose = true;

The odd part to me is that the last bar was drawn on the chart with the correct OHLC values, it just didn't pass through the Strategy's OnBarUpdate event.

Is the DataSeries for a Chart within a Strategy a different object than the DataSeries for the Strategy itself?

fwalton,

A bar is not considered closed until the opening of the next bar.
